  2. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    A specialized use of CNC plasma cutters has been in the heating, ventilating and air conditioning (HVAC) industry. Software processes information on ductwork and creates flat patterns to be cut on the cutting table by the plasma torch. This technology has enormously increased productivity within the industry since its introduction in the early ...

  3. Rotary table - Wikipedia

    en.wikipedia.org/wiki/Rotary_table

    Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel ...

  4. Flat no-leads package - Wikipedia

    en.wikipedia.org/wiki/Flat_no-leads_package

    Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide electrical connections to the PCB . [ 1 ] Flat no-lead packages usually, but not always, include an exposed thermally conductive pad to improve heat transfer out of the IC (into the PCB).

  5. Plasma display - Wikipedia

    en.wikipedia.org/wiki/Plasma_display

    A plasma display panel is a type of flat-panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches/81 cm diagonal) flat-panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions.

  6. Plasma (physics) - Wikipedia

    en.wikipedia.org/wiki/Plasma_(physics)

    Impermeable plasma is a type of thermal plasma which acts like an impermeable solid with respect to gas or cold plasma and can be physically pushed. Interaction of cold gas and thermal plasma was briefly studied by a group led by Hannes Alfvén in 1960s and 1970s for its possible applications in insulation of fusion plasma from the reactor ...

  7. Plasma parameters - Wikipedia

    en.wikipedia.org/wiki/Plasma_parameters

    The plasma collisionality is defined as [4] [5] =, where denotes the electron-ion collision frequency, is the major radius of the plasma, is the inverse aspect-ratio, and is the safety factor. The plasma parameters m i {\displaystyle m_{\mathrm {i} }} and T i {\displaystyle T_{\mathrm {i} }} denote, respectively, the mass and temperature of the ...
